Dream, and your dreams will fall short, Saint Josemaria Escriva told early members of Opus Dei. This third and final volume of the most extensively researched work on the founder of Opus Dei covers his years in Rome, from 1946 until his death there in 1975. It describes how Opus Dei overcame major obstacles and blossomed from a handful of members in Spain into a worldwide institution, with more than 60,000 members of 80 nationalities. Andres Vazquez de Prada, a Spanish diplomat, writer, and historian who knew Saint Josemaria personally, narrates the story, using previously unpublished letters, diaries, and other sources from the archives of the Prelature of Opus Dei.
